BHUNP ranger armor conversion not matching in game

[Nazghul2]

Hi I need a bit of help with the ranger armor for BHUNP on nexus (https://www.nexusmods.com/skyrimspecialedition/mods/68053?tab=description)

 

It is almost working properly (the outfit boots and armguards work, physics works), however I cannot see the groin piece, pouch and neck guard, and I also notice I see a neck seam

They display fine in inventory and can be equipped, if I open in outfit studio with BHUNP 3bbb advanced v 3 as reference it does fit perfectly, but in game they are not there.

 

Anyone had/know how to resolve this issue?

I don't know what to do since in outfit studio everything looks perfect and only these 3 pieces don't work.

Thanks!
